Description

Technical Field

[0001] This utility model relates to the field of metal processing equipment, and in particular to a longitudinal shearing device for aluminum foil processing. Background Technology

[0002] A longitudinal shearing device for aluminum foil processing is a specialized piece of equipment used to cut wide aluminum foil into the required narrow widths, playing a crucial role in the aluminum foil production process. Through a series of mechanical structures and drive mechanisms, it performs functions such as unwinding, conveying, tensioning, and longitudinal shearing of the aluminum foil, ensuring that the foil remains flat and meets the required dimensional specifications during processing.

[0003] In existing technologies, longitudinal shearing devices for aluminum foil processing typically include a base platform, unwinding rollers, tensioning rollers, conveying rollers, and cutting blades. In operation, the aluminum foil roll is first mounted on the unwinding rollers, and a motor drives the unwinding rollers to rotate and release the aluminum foil. After being tensioned by the tensioning rollers, the aluminum foil enters the conveying rollers for transport. During transport, the cutting blades longitudinally shear the aluminum foil according to a set width. However, in existing technologies, when the conveying rollers malfunction, it is usually necessary to stop the machine for repair or replacement, which leads to production interruptions and affects production efficiency.

[0004] In existing longitudinal shearing devices, if the conveyor roller malfunctions, the entire device needs to be shut down for repair or replacement. This not only increases downtime and reduces production efficiency but also easily leads to waste and discontinuity in the aluminum foil processing. Therefore, a longitudinal shearing device for aluminum foil processing is proposed to solve these problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 2 This utility model provides an embodiment of a longitudinal shearing device for aluminum foil processing, comprising a base platform 1. Four movable wheels 2 are fixedly connected to the bottom corners of the base platform 1, facilitating the movement and position adjustment of the entire device. Side plates A3 and B4 are fixedly connected to the top of the base platform 1, serving as the main support structure and providing a foundation for the installation and fixation of other components. Tensioning rollers 5 are rotatably connected to the inner sides of side plates A3 and B4. Three tensioning rollers 5 are distributed along a triangular path, effectively tensioning the aluminum foil to ensure it remains flat during processing and prevents wrinkles or loosening. A motor C is fixedly connected to the outer side of side plate A3. The output shaft of machine C passes through the outside of side plate A3 and is fixedly connected to unwinding roller 6. Unwinding roller 6 adopts a mature structure in the existing technology. Unwinding roller 6 is equipped with a special fixing structure for firmly installing aluminum foil roll. This fixing structure can ensure that the aluminum foil roll is stable and reliable during the unwinding process, and there will be no loosening or displacement, thereby ensuring the smooth unwinding of aluminum foil and the normal progress of subsequent processing. Cutting adjustment components 8 are provided above side plate A3 and side plate B4. Cutting adjustment components 8 are used to adjust the position and angle of cutting blade 803 to adapt to the cutting requirements of aluminum foil of different widths and thicknesses. Switching structure 7 is provided between side plate A3 and side plate B4. Switching structure 7 is used to switch between conveying roller 701 and spare roller 702 to realize the conveying and spare functions of aluminum foil.

[0027] Reference Figure 3 , Figure 4 The switching structure 7 includes a conveying roller 701. Slotted sliding holes A and B are respectively provided on both sides of side plates A3 and B4. A slider A703 is installed on the inner wall of slotted sliding hole A, and a slider B704 is installed on the inner wall of slotted sliding hole B. A limiting groove A and a limiting groove B are provided on the inner wall of slotted sliding hole A and B, respectively. Slider A703 and slider B704 are both cross-shaped. Slider A703 is slidably connected to the inner walls of slotted sliding hole A and limiting groove A, respectively, and slider B704 is slidably connected to the inner walls of slotted sliding hole B and limiting groove B, respectively. This sliding connection allows sliders A703 and B704 to slide up and down within slotted sliding holes A and B, and the limiting grooves A and B ensure stable movement trajectories of sliders A703 and B704, thereby achieving the switching between the conveying roller 701 and the standby roller 704. Adjusting the vertical position of roller 702, both ends of conveying roller 701 are rotatably connected to the inner side of slider A703. Motor A706 is fixedly connected to the outer side of slider A703. The output shaft of motor A706 passes through the right side of slider A703 and is fixedly connected to the end of conveying roller 701. Motor A706 provides power to conveying roller 701, enabling it to rotate and thus realize the conveying operation of aluminum foil. A spare roller 702 is rotatably connected to the inner side of slider B704. Motor B707 is fixedly connected to the outer side of slider B704. The output shaft of motor B707 passes through the right side of slider B704 and is fixedly connected to the end of spare roller 702. Motor B707 provides power to spare roller 702, enabling it to rotate. Spare roller 702 can replace conveying roller 701 to convey aluminum foil when needed.

[0028] Reference Figure 3 , Figure 4 An extension plate 708 is fixedly connected to the left side of side plate B4. A threaded rod 709 is rotatably connected through the top of the extension plate 708. A knob 7012 is fixedly connected to the top of the threaded rod 709. A threaded sleeve 7010 is threadedly connected to the surface of the threaded rod 709. A hinge A 7011 is fixedly connected to the outer side of the threaded sleeve 7010. A hinge B 7013 is fixedly connected to the left side of slider B704. A telescopic rod 705 is hinged to the left side of side plate B4. Both ends of the telescopic rod 705 are telescopic ends. The two ends of the telescopic rod 705 are respectively hinged to the inner sides of hinge A 7011 and hinge B 7013. By rotating the knob 7012, the threaded rod 709 can be rotated, thereby causing the threaded sleeve 7010 to move up and down on the threaded rod 709. In turn, the slider B704 is moved up and down through the hinge A 7011 and the telescopic rod 705, thereby realizing the up and down position adjustment of the spare roller 702.

[0029] Reference Figure 5The cutting adjustment assembly 8 includes a slide plate 801. Slide grooves 805 are respectively formed on the inner sides of side plates A3 and B4. The bottom of the slide plate 801 is embedded in the top of side plates A3 and B4. The inner wall of the slide plate 801 is slidably connected to the inner wall of the slide groove 805. The slide plate 801 can slide left and right within the slide groove 805, thereby flexibly adjusting the left and right position of the cutting blade 803 to better cooperate with the spare roller 702. Two electric cylinders 802 are fixedly connected to the top of the side plates 801. The telescopic end of the electric cylinder 802 moves through the top of the slide plate 801 and is fixedly connected to the cutting blade 803. The electric cylinder 802 can control the up and down movement of the cutting blade 803 to achieve longitudinal shearing of the aluminum foil. Two threaded grooves 804 are respectively opened on both sides of side plate A3 and side plate B4. The two threaded grooves 804 correspond to the positions of conveying roller 701 and spare roller 702 respectively. The slide plate 801 is strip-shaped. Both sides of the slide plate 801 are connected to the inner wall of the threaded groove 804 by bolts. By connecting the slide plate 801 to the threaded groove 804 with bolts, the slide plate 801 can be fixed in the adjusted position, ensuring that the cutting blade 803 can still accurately perform longitudinal shearing operation on aluminum foil after the spare roller 702 is switched to the working position, avoiding cutting deviation caused by roller switching, thereby ensuring the stability of aluminum foil processing quality, and enabling the device to complete longitudinal shearing operation stably and efficiently when the conveying roller 701 and spare roller 702 are switched.

[0030] Working Principle: When the longitudinal shearing device for aluminum foil processing is in operation, the unwinding roller 6 is first driven by motor C to rotate, allowing the aluminum foil to be released from the unwinding roller 6. The released aluminum foil passes sequentially through three tensioning rollers 5 distributed along a triangular path. The tensioning rollers 5 tension the aluminum foil to ensure that it remains flat during subsequent processing, avoiding wrinkles or loosening. The tensioned aluminum foil enters the switching structure 7, at which point motor A706 starts, driving the conveyor roller 701 to rotate, which then conveys the aluminum foil forward. During the conveying process, the sliding plate 801 is located diagonally above the conveyor roller 701. According to the width of the aluminum foil and the cutting requirements, the left and right positions of the cutting blade 803 are adjusted by the sliding plate 801 within the groove 805. Simultaneously, the electric cylinder 802 controls the up and down movement of the cutting blade 803 to perform the cutting operation on the aluminum foil. When the conveyor roller 701 malfunctions or needs replacement, the knob 7012 can be rotated. The knob 7012 rotates the threaded rod 709, causing the threaded sleeve 7010 on the threaded rod 709 to move up and down. The threaded sleeve 7010, through the hinge A7011 and the telescopic rod 705, moves the slider B704 up and down. The slider B704 moves the spare roller 702 to a position below the conveyor roller 701. Then, the motor B707 is started, driving the spare roller 702 to rotate. The spare roller 702 replaces the conveyor roller 701 to continue the aluminum foil conveying operation. At this time, the slide plate 801 is moved to a position diagonally above the spare roller 702 and fixed by bolts to the threaded connection of the threaded groove 804 to continue the longitudinal shearing step, thus ensuring the normal operation of the device.
